View.PerformHapticFeedback Method

[Android.Runtime.Register("performHapticFeedback", "(Landroid/os/vibrator/HapticFeedbackRequest;)Z", "GetPerformHapticFeedback_Landroid_os_vibrator_HapticFeedbackRequest_Handler", ApiSince=36)]
public virtual bool PerformHapticFeedback(Android.OS.Vibrators.HapticFeedbackRequest request);

[<Android.Runtime.Register("performHapticFeedback", "(Landroid/os/vibrator/HapticFeedbackRequest;)Z", "GetPerformHapticFeedback_Landroid_os_vibrator_HapticFeedbackRequest_Handler", ApiSince=36)>]
abstract member PerformHapticFeedback : Android.OS.Vibrators.HapticFeedbackRequest -> bool
override this.PerformHapticFeedback : Android.OS.Vibrators.HapticFeedbackRequest -> bool

Parameters

Returns

false if isHapticFeedbackEnabled() is false, or this View is not attached to a visible window, or the vibration usage in the provided request is not valid (i.e. neither has VibrationAttributes.USAGE_CLASS_FEEDBACK nor is VibrationAttributes.USAGE_UNKNOWN); otherwise, true, indicating that the haptic feedback request has been sent to the system. Note that true could be returned but no vibration may be produced if the service decides that the device's states do not allow for this haptic feedback (for example, the user disabled vibrations for this usage).

Attributes

RegisterAttribute

Remarks

Like performHapticFeedback(int, int), but takes a HapticFeedbackRequest.

Using a HapticFeedbackRequest allows you to make more elaborate haptic feedback requests, including setting the usage type for the requested feedback.

Specifying the usage type for your feedback allows the system to understand the context of the feedback better, and tune the haptic accordingly. When not specifying the usage type for the feedback request, or when using the other performHapticFeedback APIs, the system will do a best guess of the vibration usage based on the constant.

See VibrationAttributes to learn more about vibration usages. The usage provided for this API must be of VibrationAttributes.USAGE_CLASS_FEEDBACK, or VibrationAttributes.USAGE_UNKNOWN. Otherwise, the haptic feedback will not be played. If VibrationAttributes.USAGE_UNKNOWN is used, the system will do a best guess of the vibration usage based on the constant.

Note that, if you will be calling this API repeatedly and your HapticFeedbackRequest does not change across these repeated calls, it is recommended that you create, cache, and reuse the request object to avoid the costs of repeated object creation and garbage collection.

Parameters

Returns

The result of the perform haptic feedback operation.

Provide haptic feedback to the user for this view.

The framework will provide haptic feedback for some built in actions, such as long presses, but you may wish to provide feedback for your own widget.

The feedback will only be performed if #isHapticFeedbackEnabled() is true.
